Possible Causes

Normal pressure equalization after warm air cools, Blocked cabinet pressure equalization vent, Door gasket sticking to cabinet

How to Fix / Troubleshooting

Safety first: No electrical work is required for this issue.

  • Wait briefly: After closing the door, wait 30–60 seconds before reopening to allow pressure to equalize.
  • Check vent: Some models have a small vent or valve to equalize pressure. Ensure it is not blocked by packaging or ice.
  • Clean gasket: Wipe the door gasket and cabinet contact area with warm soapy water to reduce sticking.
  • Apply light food-safe lubricant: If the gasket sticks, a very thin film of food-safe silicone can help.
